Sneak peeks at other DC films like "Wonder Woman 1984" and "Shazam!" are also expected ... and there's always the chance for more surprises regarding upcoming Joker and "Birds of Prey" films. The studio also showed footage from "Fantastic Beasts: The Grimes of Grindelwald" and "Godzilla: King of the Monsters," while Johnny Depp himself showed up in character as the bad guy in the new Harry Potter film!

Follow along for updates from the two-hour panel, hosted by Aisha Tyler.

Aquaman

Jason Momoa proudly entered Hall H through a screen of water, showing his enthusiasm in a different way. "Its kinda like, when I'm quiet, I'm really happy," he said, in a more subdued manner I'm so proud of it.

Amber Heard, Nicole Kidman, Patrick Wilson, Yahya Abdul-Mateen II and director James Wan joined him on stage. During the Q&A, Yahya revealed he didn't know how to swim before making the movie. In the early mornings, he'd take his googles and kickboard to the pool and practice.

They all talked about the problems working with water in general. For Amber Heard, she spent most of the movie wet and cold and actually doesn't like to swim either. For Momoa, his wet denim wasn't exactly comofortbale, while Kidman said to throw as much water at her as possible.

The trailer showed Arthur's backstory, as his mom, Queen of Atlantis, has a child with a lighthouse keeper. As he grows, he learns his powers and eventually is called back to the sea by Mera (Heard) to stop his half-brother from declaring war against the surface. It was also packed with wild action, weaponized sea creatures and Aquaman proving he's worthy to be a hero.

In an additional trailer that won't be released, there was an extended sequence about how important the trident is, as well as an action sequence where Mera and Arthur fight of Black Manta and a few of his warriors. It's intense, and they both kick major ass. It ended with Momoa laughing the whole thing off.

Also, Kidman wields a trident of her own and puts it to use -- we can't wait!

Wonder Woman 1984

Gal Gadot, Chris Pine and Patty Jenkins were on hand to promo the next Wonder Woman flick, "Wonder Woman 1984."

Nobody would reveal how Pine's Steve Trevor returns after his death, with Gadot joking that he's "the water girl" on set and Pine adding he's just there for moral support. "It's something I'm super excited for everyone see the movie to find out," teased Jenkins. "It's a very important part of my movie."

As for why they're setting it in the '80s, Jenkins says that time represents "mankind at its best and worst."

While they still have 20 more weeks to go in filming, they came with footage showing Wonder Woman in the most '80s of places: the mall. There, she rescues a young girl from two men holding up the food court with guns, before flying off. There was also a shot of her running through the streets.

That was about it, but the colors and brightness of the film certainly look very different from the one before it. While we can't wait to see more, sadly fans at home won't be watching this anytime soon. Jenkins said the footage was just for the audience, sorry!

The movie hits theaters November 1, 2019.

Shazam!

Zachary Levi hit the stage to promote DC's newest solo superhero film, "Shazam!", which is about a 14-year-old boy who is given superpowers.

Levi said it was all about "wish fulfillment," and the trailer really proved that. Bily Baston is a troubled teen bouncing from foster home to foster home, who is chosen by Shazam! to take over the mantle after he stands up for his foster brother.

By simply shouting the title, Billy transforms from teenager to musclebound Levi, who still acts like a total adolescent the entire time while trying out his superpowers in the most juvenile ways possible.

It looks like "Big" with super powers and there's nothing wrong with that. Between the new Wonder Woman footage and this, it's clear Warner Bros. is trying to make their movies more hopeful, colorful and funny ... taking a turn from the ultra-serious films before them.

The movie releases April 5, 2019.

Fantastic Beasts: The Crimes of Grindelwald

Eddie Redmayne was on hand to push the new film, walking out with a wand and illuminating the entire auditorium.

First, he was asked which character he'd like to play if he were in another "Harry Potter" film. His answer: Hagrid. He then introduced the rest of the cast, before releasing the brand new trailer.

The sneak peek began with a flashback to Dumbledore (played by Jude Law) teaching a young Newt at Hogwarts. From there, it's shots of Parisian circuses as Johnny Depp's Grindelwald talks about not wanting to "sulk in the shadows" anymore. "The old ways serve us no longer," he warns. Dumbledore enlists Newt's help, after "Grindewald had a vision that he would rise to dominance over the Wizarding World," as the battle lines are drawn. It ends with the introduction of Nicholas Flamel, the alchemist who created the Philosopher's Stone.

An audience member then asked the cast how they'd use magic for good IRL. Zoe Kravitz, without hesitation: "Impeach Trump."

Law also compared his version of Dumbledore to that previously seen in the Potter films, saying he "developed a penchant for caftans and he loses his razor along the way." He added that, "He's still mischievous and he has a particular way or influencing people, slightly manipulative. And he's got secrets, which all the characters J.K. Rowling create have."

Johnny Depp then showed up, in costume as Grindelwald, to deliver one helluva speech.

The Lego Movie 2: The Second Part

The cast, including Chris Pratt and Elizabeth Banks, popped up to debut a brand new trailer for the animated film.

It takes place 5 years after the first movie, with the world seemingly turning into a "Mad Max"-type wasteland after aliens invade. "Everything was awesome, now everything is bleak," Banks' Lucy explains.

She gets kidnapped and taken to space, where Pratt's character meets up with Rex Dangervest -- also voiced by the actor. There are certainly some comparisons to his character in "Jurassic World" as well, as he trains velociraptors.

The highlight: Tiffany Haddish as a space queen who can shapeshift.

Godzilla: King of the Monsters

The King of Monsters took control of the stage next with one fierce roar, alongside co-stars Millie Bobby Brown, Vera Farmiga and Thomas Middleditch.

Brown admitted she had never seen any of the movies before, as Vera added that they weren't really her "jam" either. Brown also said it was very different than working with the Demogorgon on "Stranger Things," as her character has no superpowers here to fight back. She added they all had "neck problems after, we were always looking up so high. The Demogorgorn was just a tiny bit taller than me!

King Ghidorah, Rodan and Mothra will all pop up in the film alongside the big guy, as well as "a few more surprises."

All of them appeared in the explosive trailer, which has Vera narrating, "Our world is changing. The mass extinction we feared has already begun and we are the cause. We are the infection," she says. "The earth unleashed a fever to fight this infection, it's original and rightful rulers, the titans. For thousands of years these creatures have remained in hiding around the world. And unless all the titans are found, our planet will perish and so will we. they are the only guarantee that life will carry on."

From there, we see all the different creatures being set loose, monsters flying, blowing fire and screaming Millie Bobby Brown.
